MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
• Have all chain saw service performed by a qualified service dealer
except the items listed in the MAINTENANCE section of this manual.
• Make certain the saw chain stops
moving when the throttle trigger is
released. For correction, refer to
CARBURETOR ADJUSTMENTS.
• Keep the handles dry, clean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
tightened.
• Nonconforming replacement components or the removal of safety devices
may cause damage to the unit and
possible injury to the operator or bystanders. Use only Craftsman accessories and replacement parts as recommended. Never modify your saw.
• Maintain chain saw with care.
• Keep unit sharp and clean for better
and safer performance.
• Follow instructions for lubricating and
changing accessories.

• Check for damaged parts. Before further use of the chain saw, a guard or
other part that is damaged should be
carefully checked to determine that it
will operate properly and perform its
intended function. Check for alignment
of moving parts, binding of moving
parts, breakage of parts, mounting and
any other conditions that may affect its
operation. A guard or other part that is
damaged should be properly repaired
or replaced by a Sears Service Center
unless otherwise indicated elsewhere
in the instruction manual.
• When not in use, chain saws should
be stored in a dry, high or locked-up
place out of the reach of children.
• When storing saw, use a scabbard or
carrying case.
HANDLE FUEL WITH CAUTION
• Do not smoke while handling fuel or
while operating the saw.
• Eliminate all sources of sparks or
flame in areas where fuel is mixed or
poured.
• Mix and pour fuel in an outdoor area
and use an approved, marked container for all fuel purposes. Wipe up
all fuel spills before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting.
• Turn the engine off and let saw cool
in a non-combustible
area, not on
dry leaves, straw, paper, etc. Slowly
remove fuel cap and refuel unit.
• Store the unit and fuel in a cool, dry
well ventilated space where fuel vapors cannot reach sparks or open
flames from water heaters, electric
motors or switches, furnaces, etc.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
_'_._

Kickback Path

Avoid Obstructions

Clear The Working Area

increase the chance of kickback.
Follow manufacturer's
chain sharpening and maintenance instructions.
Check tension at regular intervals,
but never with engine running. Make
sure chain brake nuts are securely
tightened.
• Begin and continue cutting at full
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
• Use extreme caution when reentering a cut.
• Do not attempt cuts starting with the
tip of the bar (plunge cuts).
• Watch for shifting logs or other forces
that could close a cut and pinch or
fall into chain.
• Use the specified Reduced-Kickback
Guide Bar and Low-Kickback
Chain.
Avoid Pinch-Kickback:
• Be extremely aware of situations or
obstructions that can cause material
to pinch the top of or otherwise stop
the chain.
• Do not cut more than one log at a
time.
• Do not twist saw as bar is withdrawn
from an undercut when bucking.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or
wood. Never use metal to hold the
cut open.
MAINTAIN CONTROL
Stand to the left of the saw

WARNING:
Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood closes in and pinches the saw
chain in the cut. Contacting a foreign
object in the wood can also result in
loss of chain saw control.
• Rotational Kickback
can occur
when the moving chain contacts an
object at the upper tip of the guide
bar. This contact can cause the
chain to dig into the object, which
stops the chain for an instant. The
result is a lightning fast, reverse
reaction which kicks the guide bar up
and back toward the operator.
• Pinch-Kickback
can occur when the
the wood closes in and pinches the
moving saw chain in the cut along
the top of the guide bar and the saw
chain is suddenly stopped. This sudden stopping of the chain results in a
reversal of the chain force used to
cut wood and causes the saw to
move in the opposite direction of the
chain rotation. The saw is driven
straight back toward the operator.
• Pull-In can occur when the moving
chain contacts a foreign object in the
wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly stopped. This sudden stopping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw.

REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can happen.
With a basic understanding of kickback, you can reduce the element of
surprise which contributes to accidents.
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keep working area free from obstructions such as other trees, branches,
rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your
saw chain could hit while cutting.
• When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
• Keep saw chain sharp and properly
tensioned. A loose or dull chain can

Elbow

Never reverse hand positions
• A good, firm grip on the saw with both
hands will help you maintain control.
Don't let go. Grip the rear handle with
your right hand whether you are right
or left handed. Wrap the fingers of
your left hand over and around the
front handlebar, and your left thumb
under the front handlebar. Keep your
left arm straight with the elbow locked.
• Position your left hand on the front
handlebar so it is in a straight line
with your right hand on the rear handle when making bucking cuts.

KICKBACK
SAFETY
FEATURES
,_ WARNING:
The following features
are included on your saw to help reduce
hazard of kickback; however, such features will not totally eliminate this danger.
Do not rely only on safety devices. Follow all safety rules to help avoid kickback and other forces which can result
in serious injury.
• Front Hand Guard: designed to reduce the chance of your left hand
contacting the chain if your hand
slips off the front handlebar.
• Position of front and rear handlebars:
designed with distance between
handles and "in-line" with each other.
The spread and "in-line" position of
the hands provided by this design
work together to give balance and
resistance in controlling the pivot of
the saw back toward the operator if
kickback occurs.
• Reduced-Kickback
Guide Bar: designed with a small radius tip which
reduces the size of the kickback
danger zone on the bar tip. This type
bar has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in
accordance with ANSI B175.1.

CHAIN BRAKE
• Chain Brake: designed to stop the
chain in the event of kickback.
m_WARNINu:
WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast
action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the
danger zone with any hard object.
Kickback can also be caused by
pinching the saw chain along the top
of the guide bar. This action may push
the guide bar rapidly back toward the
operator. Either of these events may
cause you to lose control of the saw
which could result in serious injury or
even death. DO NOT RELY UPON ANY
OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced-kickback
guide
bars and low-kickback
saw chains reduce the chance and magnitude of
kickback and are recommended.
Your
saw has a low kickback chain and bar
as original equipment.
Repairs on a
chain brake should be made by an authorized Sears Service Center. Take
your unit to the place of purchase or to
your nearest Sears Service Center.
• Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
• Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
• Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.

,_IWARNING:

Be sure to read the

fuel handling information in the safety
rules section of this manual before you
begin. If you do not understand the
fuel handling information do not attempt to fuel your unit. Seek help from
someone that does understand the information or call the customer assistance help line at 1-800-235-5878.
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication.
The chain oiler provides continuous
lubrication to the chain and guide bar.
Be sure to fill the bar oil tank when you
fill the fuel tank (Capacity = 6.8 ft. oz.).
Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating shown by smoke coming from the
chain and/or discoloration
of the bar.
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oil
is not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. The oil output
is automatically metered during operation. Your saw will use approximately
one tank of bar oil for every tank of fuel
mix. Always fill the bar oil tank when
you fill the fuel tank.
FUELING ENGINE
,_IWARNING:
Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality 2-cycle air-cooled engine oil.
We recommend Craftsman brand oil.
Mix gasoline and oil at a ratio of 40:1.
A 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline. Included with this saw is a
3.2 ounce container of Craftsman
brand oil. Pour the entire contents of
this container into 1 gallon of gasoline
to achieve the proper fuel mixture.
DO NOT USE automotive oil or boat oil.
These oils will cause engine damage.
When mixing fuel follow the instructions
printed on the oil container.

Once oil is added to the gasoline,
shake container momentarily to assure
that the fuel is thoroughly mixed. Always read and follow the safety rules
relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage. To avoid engine
problems, the fuel system should be
emptied before storage for 30 days or
longer. Drain the gas tank, start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel
next season. See STORAGE instructions
for additional information.
Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
See the STORAGE section for additional information.
CHAIN BRAKE
Ensure chain brake is disengaged by
pulling the front hand guard back toward the front handle as far as possible. The chain brake must be disengaged before cutting with the saw.
_IWARNING:

The chain must not

move when the engine runs at idle
speed. If the chain moves at idle
speed, refer to CARBURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can
cause serious burns.

call 1-800-235-5878.
CHAIN BRAKE
Z_

WARNING:
If the brake band is
worn too thin it may break when the
chain brake is triggered. With a broken
brake band, the chain brake will not
stop the chain. The chain brake must
be replaced if any part is worn to less
than 1/32" thick. Repairs on a chain
brake should be made by your Sears
Service Center. Take your unit to the
place of purchase or to the nearest
Sears Service Center.
• This saw is equipped with a chain
brake. The brake is designed to stop
the chain if kickback occurs.
• The inertia-activated
chain brake is
activated if the front hand guard is
pushed forward, either manually (by
hand) or automatically (by sudden
movement).
• If the brake is already activated, it is
disengaged by pulling the front hand
guard back toward the front handle
as far as possible.

,_WARNING:
When performing the
following procedure, the engine must
be turned off.
Grip the rear handle with your right
hand and the front handle with your left
hand. Hold the chain saw approximately 14" (35 cm) above a stump or
other wooden surface. Release your
grip on the front handle and use the
weight of the saw to let the tip of the
guide bar fall forward and contact the
stump. When the tip of the bar hits the
stump, the brake should activate.
OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION in the MAINTENANCE
section.
• Cut wood only. Do not cut metal,
plastics, masonry, non-wood building
materials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
• Practice cutting a few small logs using the following steps. This will help
you get the "feel" of using your saw

before you begin a major sawing operation.
• Squeeze the throttle trigger and allow the engine to reach full speed
before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the
entire time you are cutting.
• Allow the chain to cut for you. Exert
only light downward pressure.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wear can occur.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop engine before setting saw down.
TREE FELLING TECHNIQUES
'_WARNING:

Check for broken or

dead branches which can fall while
cutting causing serious injury. Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc.
• Carefully plan your sawing operation
in advance.
• Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill
after it is felled.
• Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions include:
• The wind direction and speed.
• The lean ofthe tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the direction of tree lean.
• Weight and branches on one side.
• Surrounding trees and obstacles.
• Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator.
• Make sure there is enough room for
the tree to fall. Maintain a distance of
2-1/2 tree lengths from the nearest
person or other objects. Engine
noise can drown out a warning call.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend to fall in
the direction of the notch.
NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting
ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
• Make notch cut by cutting the top of
the notch first. Cut through 1/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut, remove the wedge of wood from tree.
First cut

Felling cut here
/

NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of
fall. To avoid kickback and chain
damage, use wood or plastic wedges,
but never steel or iron wedges.
• Be alert to signs that the tree is
ready to fall: cracking sounds, widening of the felling cut, or movement in
the upper branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
• DO NOT use your saw to cut down a
partially fallen tree. Be extremely
cautious with partially fallen trees
that may be poorly supported. When
a tree doesn't fall completely, set the
saw aside and pull down the tree
with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
_ik WARNING:

Notch

, _._

Second out'J"

._.

"_-_[-'" z.

_nge

• After removing the wood from the
notch, make the felling cut on the opposite side of the notch. This is done
by making a cut about two inches
higher than the center of the notch.
This will leave enough uncut wood
between the felling cut and the notch
to form a hinge. This hinge will help
prevent the tree from falling in the
wrong direction.

Do not stand on the

log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.
IMPORTANT POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• Use a sawhorse to cut small logs.
Never allow another person to hold
the log while cutting and never hold
the log with your leg or foot.
• Do not cut in an area where logs,
limbs, and roots are tangled. Drag logs
into a clear area before cutting them
by pulling out exposed and cleared
logs first.

LIMBING AND PRUNING

guard against kickback.
Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when ]imbing or pruning. Allowing such contact can result in serious injury.

• Keep the tree between you and the
chain.
• Remove larger branches with the
cutting techniques described in
BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut small
and freely hanging limbs. Undercutting could cause limbs to fall and
pinch the saw.

_LWARNING:

PRUNING

,_L WARNING:

Be alert for and

Never climb into a

tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
• Watch out for springpoles.
Springpo]es are small size limbs
which can whip toward you, or pull
you off balance. Use extreme caution when cutting small size limbs.
• Be alert for springback from any
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Frequently clear branches out of the
way to avoid tripping over them.
LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.

_WARNING:
Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder. Get a professional to do the job.
• Make your first cut 1/3 of the way
through the bottom of the limb. This
cut will make the limb sag so that it
falls easily on the second cut.
• Next make the second cut an overcut all the way through the limb,
• Finish the pruning operation by using
an overcut so that the stump of the
limb protrudes 1 to 2 inches from the
trunk of the tree.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cover items that have been subjected to
operator abuse or negligence. To receive full value from the warranty, the
operator must maintain unit as instructed in this manual. Various adjustments
will need to be made periodically to
properly maintain your unit.
• Once a year, replace the spark plug,
air filter element, and check guide
bar and chain for wear. A new spark
plug and air filter element assures
proper air-fuel mixture and helps
your engine run better and last longer.
CHECK FOR DAMAGED
OR
WORN PARTS
Contact Sears Service Center for replacement of damaged or worn parts.
NOTE: It is normal for a small amount
of oil to appear under the saw after engine stops. Do not confuse this with a
leaking oil tank.
• ON/STOP Switch - Ensure ON/STOP
switch functions properly by moving
the switch to the STOP position.

Make sure engine stops; then restart
engine and continue.
• Fuel Tank - Do not use saw if fuel
tank shows signs of damage or

CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
After each use, ensure ON/STOP
switch is in the STOP position, then
clean all sawdust from the guide bar
and sprocket hole.
To maintain guide bar:
• Move ON/STOP switch to STOP.
• Loosen and remove chain brake
nuts and chain brake. Remove bar
and chain from saw.
• Clean the oil holes and bar groove
after each 5 hours of operation.

CARBURETOR
ADJUSTMENT
'_WARNING:

at initial settings is acceptable, no
further adjustments are necessary.
If engine does not start, refer to the
TROUBLESHOOTING TABLE. If still
unable to remedy situation, call
1-800-235-5878.

The chain will be

moving during most of this procedure.
Wear your protective equipment and
observe all safety precautions. During
the low speed mixture adjustment recheck idle speed after each turn of the
screw. The chain must not move at idle
speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the carburetor. If you require further assistance or are unsure about performing
this procedure, call our customer assistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, dirty fuel filter,
or flooding may give the impression of
an improperly adjusted carburetor.
Check these conditions before adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the following conditions:
• Chain moves at idle. See IDLE
SPEED-T under adjusting procedure.
• Saw will not idle. See IDLE SPEED-T
and LOW SPEED MIXTURE-L under
adjusting procedure.
• Engine dies or hesitates when it
should accelerate. See ACCELERATION CHECK under adjusting
procedure.
• Loss of cutting power. See HIGH
SPEED MIXTURE - H under adjusting
procedure.
There are three adjustment screws on
the carburetor. They are labeled H, L,
and T. They are located in the area just
above the primer bulb.
ADJUSTING
PROCEDURE
CAUTION:
Do not force plastic limiter
caps on screws beyond the built-in
stops or damage will occur.
Initial Settings
1. Turn both mixture screws (L and H)
counterclockwise
until they stop.
2. Turn the idle speed screw (T)
clockwise until it stops. Then turn it
counterclockwise
4 and 1/2 turns.
3. Start engine and let it run for 3 minutes, then proceed to adjust
screws according to the instructions below. If engine performance

Idle Speed-T
Allow engine to idle. If the chain
moves, idle is too fast. If the engine
stalls, idle is too slow. Adjust speed
until engine runs without chain movement (idle too fast) or stalling (idle too
slow).
• Turn idle screw (T) clockwise to increase engine speed.
• Turn idle screw (T) counterclockwise
to decrease engine speed.
Low Speed Mixture-L
Allow engine to idle. Then accelerate
the engine and note performance. If
engine hesitates, bogs down, or
smokes during acceleration, turn low
speed mixture screw (L) clockwise in
1/16-turn increments until performance
is satisfactory. Repeat this procedure
as necessary for proper adjustment.
After completing adjustments, check
for acceleration and chain movement
at idle. Reset if necessary.
High Speed Mixture-H
DO NOT operate engine at full throttle
for prolonged periods while making adjustments. Damage to the engine can
occur. Make a test cut. Based on performance of the saw while cutting, adjust the high speed mixture setting in
1/16-turn increments as follows:
• Turn the high speed mixture screw (H)
clockwise until saw has good power in
the cut with no hesitation. Do not adjust by sound or speed, but judge by
how well the saw performs in the cut.
• Turn the high speed mixture screw
(H) counterclockwise
if the saw has
speed, but dies in the cut or lacks
power in the cut.
After completing adjustments, check
for acceleration and chain movement
at idle. Reset if necessary.
Acceleration
Check
If the engine dies or hesitates instead of
accelerating, turn the low speed mixture
screw (L) counterclockwise until you
have smooth acceleration with no chain
movement at idle.

,_ WARNING:
Perform the following
steps after each use:
• Allow the engine to cool, and secure
the unit before storing or transporting.
• Store chain saw and fuel in a well
ventilated area where fuel vapors
cannot reach sparks or open flames
from water heaters, electric motors or
switches, furnaces, etc.
• Store chain saw with all guards in
place and position chain saw so that
any sharp object cannot accidentally
cause injury.
• Store chain saw well out of the reach
of children.
SEASONAL STORAGE

end of the season or if it will not be
used for 30 days or more.
If your chain saw is to be stored for a
period of time:
• Clean saw thoroughly before storage.
• Store in a clean dry area.
• Lightly oil external metal surfaces
and guide bar.
• Oil the chain and wrap it in heavy paper or cloth.
FUEL SYSTEM
Under Fueling Engine in the Operating
Section of this manual, see message
labeled IMPORTANT regarding the

use of gasohol in your chain saw.
Fuel stabilizer is an acceptable alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
containers. Run engine at least 5 minutes after adding stabilizer.
Craftsman 40:1,2-cycle
engine oil (air
cooled) is especially blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to your
fuel tank.
